Abstract (en)
[origin: EP3611919A1] The present invention provides an analog read circuit coupled to a pixel output end of a pixel circuit. The analog read circuit includes an amplifier and a sensing multiple sampling unit, wherein, in a selection interval, the sensing multiple sampling unit respectively implements a plurality of sensing sampling operations on pixel values at the pixel output end at a plurality of sensing sampling times to generate a plurality of sensing sampling results; and in an output interval, the sensing multiple sampling unit implements a sensing averaging operation on the plurality of sampling results. The amplifier outputs a read result that is related to a sensing average of the plurality of sensing sampling results.
